settings for all 250 addresses.

2.Set the jumpers JP4 and JP5. If the IQ–P.I.P.– DSP is being installed into a PIP2-compatible or Macro-Tech 5000VZ amplifier, move both jumper JP4 and JP5 on the IQ circuit board to the “OUT” position (Figures 2.1 and 3.6). Set both JP4 and JP5 to the “IN” position for all other amplifiers.

3.2 Prepare the Amplifier

3.Turn down the level controls (full counter- clockwise) and turn off the amplifier.

4.Disconnect the amplifier’s power cord.

5.Remove the existing P.I.P. or cover panel from the amplifier back panel (two screws). For PIP2 amplifi- ers this may involve disconnecting the P.I.P. from a PIP2 input adapter (Figure 3.4). If a PIP2 input adapter is already present, do not remove the rib- bon cables from the adapter. Otherwise you will have to reconnect them in Step 9.

6.Set the amplifier input sensitivity to 0.775 V. (See the amplifier’s Reference Manual.)

3.3Install the IQ–P.I.P.–DSPinto the Amplifier

7.Carefully ground yourself to the chassis of the amplifier before installing the IQ–P.I.P.–DSP. It is a good idea to maintain ground contact be- tween yourself and the amplifier while inserting the module into the P.I.P. card rails (standard P.I.P.-compatible amplifiers) or the PIP2 connec- tor (PIP2-compatible amplifiers).

8.Install the IQ–P.I.P.–DSPinto the amplifier:

Standard P.I.P. Amplifiers: Align the edges of the IQ–P.I.P.–DSP in the P.I.P. card rails and firmly push the unit in until it is seated against the mounting bracket (see Figure 3.3).

PIP2 Amplifiers: Connect the PIP2 input adapter to the two input cables of the amplifier (Figure

3.4). Notice that the PIP2 input adapter should be positioned with the P.I.P. edge connector on top facing away from the amplifier. The 20 pin cable (A) is connected first then the 18 pin cable

Next, insert the edge connector of the IQ–P.I.P.– DSP into the PIP2 input adapter (see Figure 3.5)

and insert the assembly into the P.I.P. opening in the back of the amplifier.

9.Tighten the two P.I.P. mounting screws until the P.I.P. is secured to the amplifier back panel.

3.4 Install the Wiring

10.Connect the IQ–P.I.P.–DSP to the IQ System via the Crown Bus. See Section 3.6 for full in- structions.

11.Connect the audio signal wiring to the IQ– P.I.P.–DSP. This includes the XLR input wiring and, if desired, the phone jack daisy chain wir- ing. See Section 3.7 for full instructions. Note: The supplied EMI suppression core must be used on the daisy chain outputs for the IQ–P.I.P.– DSP to comply with FCC and EC EMC regula- tions (see Section 3.7).

12.Connect the amplifier back to the AC recep- tacle. Note: The IQ–P.I.P.–DSP may require an

external power supply in some amplifiers. See
